Clinical significance of white gastric crypt openings observed via magnifying endoscopy

Figure 3 A case with an early undifferentiated-type gastric cancer in the middle of the corpus. A: A 67-year-old woman was found to have a depressed undifferentiated-type gastric cancer about 20 mm in diameter in an area found endoscopically to be non-atrophic; B: Magnifying endoscopy image showing minute round pits in uninvolved corpus mucosa; C: The whiteness of the crypt openings is "dense white pit" type; they resemble snowballs; D: Microscopic examination of uninvolved corpus mucosa revealed marked lymphocyte and neutrophil infiltration in the lamina propria and neutrophil infiltration within the foveolar lumens (HE stain, × 100).
